Title: Laser drive circuit
Inventor: MATSUI SHOICHI
IPC: G11B7/125
Filed: 1988-04-05
Abstract: PURPOSE:To obtain a radiated optical intensity always constant even if ambient temperature is changed by determining a current from a 2nd constant current circuit by a current from a 1st constant current circuit giving a current to a semiconductor laser at reproduction of signal. CONSTITUTION:The current flowing to the semiconductor laser 1 at signal reproduction depends on the 1st constant current circuit 6 and the current flowing to the 1st constant current circuit 6 is the sum of a voltage decided by thee resistance division and a voltage being the result of conversion of the current from an output monitor use PIN photodiode 2. When the radiated light intensity of the semiconductor laser 1 is increased, the current from the PIN photodiode 2 is increased and the current from the 1st constant current circuit 6 is decreased. If the output radiated light intensity is weakened conversely, the current from the 1st constant current circuit 6 is increased by the opposite operation to keep the radiated light intensity of the semiconductor laser 1 constant. Thus, even if ambient temperature is changed, the radiated light intensity is kept constant.

Filed: 1986-04-11
Abstract: PURPOSE:To obtain a molded item with a rugged pattern at the lamination interface by a method wherein a rugged pattern is formed in such a manner that a tongued-and- grooved face gradually vanishes from the end face of a mouthpiece land to the inner part on at least one side face of the intersection of mouthpiece lands, which respectively communicate to a main extruder and to an auxiliary extruder. CONSTITUTION:An end face having a rugged pattern in the direction traversing the extruding plastic flow (width direction) on the side face of a mouthpiece and 3 at the intersection 8 of the mouthpiece land 3 communicating to an extruder A and a mouthpiece land 4 communicating to an auxiliary extruder B. The rugged pattern is formed in such a manner that a tongued-and-grooved face gradually vanishes toward the inner part of the mouthpiece land 3. For example, only on the under surface of a block-shaped liner 5, which is fitted to the intersection 8 of the mouthpiece lands 3 and 4, tapered tongued parts 6 are formed. By meeting molten plastics sent from the main extruder and from the auxiliary extruder in a mouthpiece, a flat sheet-like double layer molded item having one of various kinds of rugged patterns, each of which is determined by the rugged pattern of the intersection, can be obtained. The formed rugged pattern does not vanish due to wear, because of being imbedded.

Filed: 1990-03-30
Abstract: PURPOSE:To monitor the quality of a current line on the reception side by detecting coincidence/noncoincidence between error detection data sent from the transmission side and that on the reception side at the time of the non- speech state. CONSTITUTION:At the time of non-speech, dial pulses are not changed equally to the transmission side of a voice multiplexer 1, and the non-speech state is detected by a time measurer 64 and an AND circuit 65 when the '1' (open) state continues for a certain time or longer. Then, the result of coincidence/ noncoincidence between a PN pattern as error detection data from a PN pattern generator (PTN) 21 on the transmission side and a PN pattern from a PTN 61 on the reception side is outputted from an AND circuit 66. Thus, the quality of the transmission line is checked on the reception side.

Title: Method for filling sliver in container and device thereof
Inventor: KRIEGLER ALBERT
IPC: B65H54/80
Filed: 1999-03-26
Abstract: PROBLEM TO BE SOLVED: To provide advantage from the point of cost, and prevent the danger of flying in all direction and damaging of slivers without requiring the slit of a container. SOLUTION: When slivers 2 are filled in a container 3, the bottom 33 of the container is descended from an upper terminal position to a lower terminal position according to the progress of filling process. In this case, field force is generated between two members which exist in both sides of a peripheral wall 32 of the container, the bottom of the container is supported by a member which exists in the container, and the member is held at the same height as a member moved according to a desired adjusting height of the bottom of the container through the field force and arranged in the outside of the container. In order to descend the bottom of the container, either of both members in the case where the field force is formed between them is moved relatively against the other member in a direction of the lower terminal position of the bottom of the container.  The other member is followed a first member through the field force until both members are contraposed at the same height again. In this case, it is possible to generate stationary force steered for the peripheral wall and for forming braking force opposed to the weight of the bottom of the container accepted a load in order to support the bottom of the container.

Title: Production for patterned fresnel hologram
Inventor: TANIGUCHI YUKIO
IPC: B42D15/10
Filed: 1982-05-18
Abstract: PURPOSE:To produce easily a pattern-shaped Fresnel hologram which is difficult to forge and is easily distinguished from false holograms and is superior in decorativity, by providing a pattern-shaped Fresnel hologram. CONSTITUTION:A photosensitive substrate exposed to an interference light is exposed to a light 9 for exposure through a mask pattern 8. Though a proper light-transmissive pattern can be used as the mask pattern, a pattern matched not to damage the transmission pattern is desirable. Ultraviolet rays, especially, rays having 0.25-0.45mum wavelength emitted from a light source such as an extra-high pressure mercury vapor lamp, a high pressure mercury vapor lamp, a low pressure mercury vapor lamp, a carbon arc, a xenon arc, or the like are used desirably as the light 9 for exposure, and it is desirable that irradiation is so performed that the integral exposure is >=10mJ/cm<2>. By this exposure through the mask pattern, a photosensitive resin layer in parts exposed to light is decomposed when the photosensitive resin layer is positive, and this photosensitive resin layer in these parts is hardened when the photosensitive resin layer is negative, and the pattern-shaped Fresnel hologram is obtained by the development using a developer.
